Impulsiveness is a personality trait that refers to the tendency to act on impulse or without thinking about the consequences. People who are high in impulsiveness may have difficulty controlling their impulses and may make decisions or take actions without considering the potential risks or negative outcomes. Impulsiveness can manifest in various ways, such as impulsive behavior, impulsive decision-making, and impulsive responses to situations. The Barratt Impulsiveness Scale (BIS-11) is a widely used measure of impulsiveness. It assesses three different dimensions of impulsiveness: non-planning impulsiveness, motor impulsiveness, and attentional impulsiveness. Non-planning impulsiveness refers to the tendency to act impulsively without thinking about the consequences or planning ahead. Motor impulsiveness refers to the tendency to act impulsively on the spur of the moment. Attentional impulsiveness refers to the tendency to be easily distracted and to have difficulty focusing on a task.
